Question

suppose that the world is comprised of two countries: X and Y. Because of the absence of centralized world governance, the control of global externalities is particularly challenging, which is the case with greenhouse gases linked to climate change. The entries in the following Payoff Table describe each country's well-being under different abatement patterns:

X\Y	No Abate	Abate
No Abate	12,12	24,8
Abate	8,24	20,20

Now suppose that the game is repeated indefinitely. Define the concepts of Trigger Strategies and also the concept of Business as Usual Strategies for the repeated game. Verify that trigger strategies supporting cooperative payoffs (20,20) constitute a non-cooperative equilibrium of the repeated game when δ=0.8. Are trigger strategies still an equilibrium when δ=0.30? Explain intuitively why and verify that Business as Usual still is an equilibrium in this case.
